Possible Causes
Defective door switch, Misaligned door latch, Faulty Start button on keypad, Failed relay on main control board
How to Fix / Troubleshooting
Safety First: Unplug the microwave before accessing door switches or control panel.
- Check door indicator: If the display does not show that the door is closed, the door switch system is suspect.
- Try multiple keys: If some keys work (e.g., clock) but Start does not, the keypad may be partially failed.
- Inspect door latch: Ensure the door closes firmly and the latch hooks are intact.
- Test door switches: Access the door switch assembly and test each switch with a multimeter. Replace any defective switches or broken latch bracket.
- Control issues: If switches and keypad test good, the main control board’s relay or logic may be faulty and require replacement.
